/* NATI METHOD brand, measured from natimethod.sk (computed styles, 27. 8. 2026)
   rather than sampled from a screenshot.

   Two rules hold the whole palette together:

   - The gold is a gradient, not a flat colour. The client's primary button is
     linear-gradient(172deg, #F8C28E, #B86626); one hex cannot stand in for it.
   - Gold is fill, edge and mark — never text. Their heading gold #D59056 sits
     at 2.5:1 on the warm ground, under the 3:1 floor for even large text. It
     works on their site because it appears in 76 px display headings; here it
     would be statements and error messages. Text stays on --text at 11.8:1.

   The gradient carries no text either. Measured across its length, light text
   runs 1.5:1 to 4.0:1 and dark text 7.8:1 down to 3.0:1 — neither survives the
   whole sweep. So anything with a label on it uses --gradient-fill, the light
   quarter of the same gradient, where the brand's own dark text reads at 6-8:1.
   The full gradient is kept for the progress bar, which carries no text. */

/* Self-hosted because the site's CSP is default-src 'self' — a Google Fonts
   link would be blocked and the page would silently fall back. Both families
   are variable and OFL-licensed; see fonts/OFL.txt. */
